To all whom it may concern:

Beit known that 1, CHARLES BARTON, of Brandon, in the county of Warwick,England, gentleman, have invented certain new and useful Improvements inHydrocarbon-Burners for Lamps or Stoves, (for which I have applied forLetters Patent in Great Britain, dated September' 26, 1884, No. 12,822,)of which the following is a specification.

Thisinvention relates to an improved vaporburner by which the usualcotton wicks heretofore used are done away with, and the expense,trouble, and danger incident to the use of said wicks, also thetrimmingand renewing of the same are dispensed with.

My invention consists of a burner composed of an exterior tube, aninterior wick-tube, and an intermediate layer orlling ofcarbon,charcoal, pumice-stone, plaster-of-paris, sand, or likelasting andporous substance, or cotton,

sponge, or asbestus, or like suitable fibrousv substance. The exteriortube is made of glass, porcelain, or like material, being a more or lessbad conductor of heat, and not likely to become unduly heated so as toflash the oil. The upper end of the outer tube is iiattened and dished,so as to form a suitable burner, that directs the vapors to form theshape of the flame. In the inner tube is arranged a wick that projectsbelow the edge of the outer burner-tube,and serves to produce and ignitethe oily vapors,which are obtained by heating the saturated intermediatefilling ot' plasterof-paris or other porous material.

In the accompanying drawings, Figure l represents a side elevation of myimproved hydrocarbon-burner. Fig. 2 is a plan; Fig. 3, a verticalcentral section of the same, and Fig. 4 a vertical central section ofthe top of the burner, showing the details slightly varied.

Similar letters of reference indicate corresponding parts.

A in the drawings represents a tube of glass, porcelain, or othervitreous or like bad heatconducting material. At the inside of this tubeis preferably placed one or more smaller tubes, C, of glass, porcelain,metal, or Aother suitable material, in which the wick D is placed. Thespace between the outer tube, A, and the inner wick-tube, C, is filledwith plaster-of paris or other suitable porous material, B. By practicaltests I have found that a plaster-of-paris filling has given excellentresults.

The plaster-of-paris B may be so filled in that the inner tube, C, isfixed; or the tube may be simply slipped in or removed from the hole inthe plasterbf-paris lling, as desired.

The filling of plaster-of-paris or other suitable porous material isexposed at its lower end to contact with the oil, which latter risesthrough said porous material by capillary attraction.

The wick D may also be placed directlyinto the porous filling withoutemploying any Wicktube C; but it is preferable to use the innerwick-tube, as the ignition-wick can then be inserted and removed withgreater facility when it is desired to do so.

The top of the tube A is dished and flattened, so as to form a smalldepression on each side of theinnertube, G, and above the porousmaterial B. This leaves a space for the generation of the oily vaporscaused by the small wick D when first lighted, so as to heat the"'lattenedwalls of the top of the tube A.

The height of the porous material and of the inner wick-tube, C, abovethe porous plaster or other material B may be varied as required. Fig. 4shows the wick-tube raised above the porous filling, While in Fig. 3 itis shown nearly flush therewith.

In Fig. 4 the porous filling is molded so as to dish toward the wick,while in Fig. 3 it is molded so as to dish from the wick-tube toward theouter tube, A.

The wick is consumed very slowly' when the burner is lighted. It burnsdown to the edge of the wick-tube, so as to heat the flattened walls ofthe outer tube,and also the top of the plaster or like porous material,so that the oil rising through theporous material is vaporized andburned as a gas, instead of being burned with a consuming wick, asheretofore. The burner is made long enough, so as to nearly reach thebottom of the reservoir or font and secure the combustion of the oil orspirit therein.

Burners made according to my invention are safer, and do not smoke, asusual with cotton wicks. They also secure a more perfect combustionofthe oil or spirit andinsure a less consumption thereof, andconsequently afford greater facilities for keeping lamps or stoves cleanand in order. It is obvious that two or more of my burners may becombined, so as to form duplex77 or multiplex7 burners, as required bythe lamp or stove.

rlhe necessary connection or cap for connecting the burner with thereservoir is not shown in the drawings, as this depends on the style ofthelamp or stove for which the burner is used.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A vapor-burner consisting of a tube provided witha porous packing,said packing being provided with a longitudinal openingand exposed to contact with the oil at its lower end, and a Wickinserted in said opening, substantially as described.

2. Avapor-burner consisting of an inner and an outer tube, a porouspacking between said tubes,exposed at its lower end, and a wickinsertedin the inner tube, substantially as described.

3.. A vapor-burner consisting of a tube prof vided with a porouspacking, said packing being provided with a longitudinal opening andexposed to contact with the oil at its lower end, and a wick inserted insaid opening, the upper end of said tube being extended above saidpacking, substantially as described.

4. A vapor-burner comprising an outer and an inner tube and a porouspacking between said tubes,exposed at itslower end, the upper end ofsaid outer tube being extended above said packing, substantially asdescribed.

5. A Vaporburner comprising an outer and an inner tube and a porouspacking between said tubesexposed at its lower end, the upper end ofsaid outer tube being extended above said packing and recessed atopposite sides, substantially as described.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
